DETAILED DESCRIPTION

Embodiments of the present disclosure are described in detail with reference to embodiments thereof as illustrated in the accompanying drawings. References to “one embodiment,” “an embodiment,” “some embodiments,” etc., indicate that the embodiment(s) described may include a particular feature, structure, or characteristic, but every embodiment may not necessarily include the particular feature, structure, or characteristic. Moreover, such phrases are not necessarily referring to the same embodiment. Further, when a particular feature, structure, or characteristic is described in connection with an embodiment, it is submitted that it is within the knowledge of one skilled in the art to affect such feature, structure, or characteristic in connection with other embodiments whether or not explicitly described.

The following examples are illustrative, but not limiting, of the present embodiments. Other suitable modifications and adaptations of the variety of conditions and parameters normally encountered in the field, and which would be apparent to those skilled in the art, are within the spirit and scope of the disclosure.

Bags are often used for containing and transporting items. For example, bags may be used to contain items purchased at a store and to transport those items in a trunk of a car or on a bed of a truck. However, bags placed in a trunk or on a truck bed sometimes slide around and/or spill their contents during transport, which may be distracting to a driver or create a mess. It may therefore be desirable to more securely place a bag in a trunk or on a truck bed in order to reduce the likelihood of the bag sliding around and/or spilling its contents during transport. It may also be desirable to store bags when they are not being used so that the bags do not needlessly take up space in a user's car, truck, home or other location and/or so that a user can easily find the bags when needed.

Some embodiments of the present disclosure provide a bag that can be magnetically attached to another bag via magnet units located on each bag. When two or more bags are magnetically attached, the bags may help hold each other upright. The bags may be configured such that magnet units on the bags can be attached when the bags are arranged in a line, a row, or a matrix. The magnet units on the bags may also be configured to disconnect from each other so that the bags can be rearranged and/or used independently of each other.

In some embodiments, a base is provided. The base may be attachable to a trunk of a car or a bed of a truck. The base may include a magnet unit such that a bag with a magnet unit can be magnetically attached to the base. When the bag is attached to the base, the bag may be more securely attached to the trunk or truck bed, thereby reducing the likelihood that the bag will slide. When the bag is attached to the base, the base may also help hold the bag upright. In some embodiments, the base may not include a magnet unit but may comprise metal or other magnetic material such that the bag may be magnetically attached to the base. In some embodiments, the base may comprise a pre-existing component of vehicle, such as a door, side panel, floor board, floor, metal fixture, or other component.

In some embodiments, the bag may include multiple magnetic units that can be magnetically attached to each other. In some embodiments, the bag may also be convertible between a flattened configuration and an expanded configuration. When multiple magnet units are connected to each other, the connected magnet units may help hold the bag in the flattened configuration.

These and other embodiments are discussed below in more detail with reference to the figures.

FIG. 1 illustrates a bag 100 according to some embodiments. Bag 100 may include a main body 200 defining a storage compartment 210, a bag handle 300, and one or more magnet units 400.

Bag handle 300 may be attached to main body 200 such that bag 100 can be carried by bag handle 300. Bag 100 may be used to transport an object therein. For example, the object may be contained within storage compartment 210 of main body 200, and transported along with bag 100 by a user carrying bag 100 by bag handle 300.

Magnet units 400 may be attached to main body 200 and configured to connect by magnetic force to: one or more magnet units disposed on a second bag (e.g., as shown in FIG. 2), one or more magnet units disposed on a base (e.g., as shown in FIG. 3), other magnet units 400 disposed on main body 200 (e.g., as shown in FIG. 4), a fixed base comprising a magnetic material, or combinations thereof. When magnet units 400 are connected to one or more magnet units disposed on a second bag (e.g., as shown in FIG. 2), the first bag and the second bag help hold each other upright. When magnet units 400 are connected by magnetic force to one or more magnet units disposed on a base (e.g., as shown in FIG. 3), the base helps hold the bag upright and helps prevent the bag from sliding (when the base is attached to a portion of a trunk or truck bed). When magnet units 400 are connected to each other (e.g., as shown in FIG. 4), the connected magnet units 400 help hold the bag in a flattened configuration.

In some embodiments, bag 100 is intended to be reusable. However, in other embodiments, bag 100 may be intended to be disposable or include disposable portions.

In some embodiments, bag 100 may comprise luggage or a gym bag.

Main body 200 of bag 100 may have any shape sufficient to transport an item. For example, main body 200 may be shaped as a rectangular prism, as illustrated in FIG. 1.

In some embodiments, main body 200 may be formed of a bottom panel 220 and one or more side panels 230. In the illustrated embodiments, bottom panel 220 is rectangular. However, bottom panel 220 may have any suitable shape including, for example, a triangular, circular, square, or hexagonal shape. Side panels 230 may be connected to other side panels 230 at side edges 240, and side panels 230 may be connected to bottom panel 220 at bottom edges 250. Side edges 240 and bottom edges 250 may be formed by folds 260, and thus side panels 230 and bottom panel 220 may be at least partially continuous with each other across side edges 240 and bottom edges 250.

Main body 200 may be formed of any suitable material, including, for example, paper, woven or non-woven fabric (including, for example, polyester, polypropylene, nylon, cotton, hemp, burlap), plastic, or other suitable material.

Main body 200 may be open at one end or may be closeable with use of a fastener (e.g., a zipper).

In some embodiments, main body 200 may include a lining 270 (not shown) for reinforcement, insulation, or aesthetic purposes, and an exterior shell 280 (not shown). Lining 270 and exterior shell 280 may be formed of any suitable material, including, for example, paper, woven or non-woven fabric (including, for example, polyester, polypropylene, nylon, cotton, hemp, burlap) or plastic. In some embodiments, lining 270 and exterior shell 280 may be formed of the same material. In other embodiments, lining 270 and exterior shell 280 may be formed of different materials. For example, exterior shell 280 may be formed of 600 D polyester and lining 270 may be formed of 150 D polyester. As another example, exterior shell 280 may be formed of 600 D polyester and lining 270 may be formed of a reflective film laminated with 4 mm PE foam.

In some embodiments, a pattern, logo, text, or other embellishment 290 may be applied to main body 200 (e.g., via a silk-screening process).

Main body 200 may be convertible between an expanded configuration (e.g., as shown in FIG. 1) and a flattened configuration (e.g., as shown in FIG. 4), and vice versa. In the expanded configuration, main body 200 may be used to contain an object. In the flattened configuration, main body 200 may take up less space than in the expanded configuration for more efficient storage of bag 100.

To facilitate conversion between an expanded configuration and the flattened configuration, main body 200 may include expansion folds 260. For example, in the illustrated embodiment, main body 200 includes gusset folds 262 on side panels 230. When gusset folds 262 are unfolded, main body 200 is in the expanded configuration, and when gusset folds 262 are folded, main body 200 is in the flattened configuration.

In some embodiments, main body 200 may include one or more areas of webbing. For example, webbing may form exterior and/or interior pockets on main body 200 for additional storage.

One or more magnet units 400 may be fixed to main body 200.

Magnet unit 400 may be configured to connect by magnetic force to: one or more magnet units disposed on a second bag (e.g., as shown in FIG. 2), one or more magnet units disposed on a base (e.g., as shown in FIG. 3), other magnet units 400 disposed on main body 200 (e.g., as shown in FIG. 4), or a fixed base comprising a magnetic material, or combinations thereof. Magnet unit 400 may also be configured to disconnect from the one or more magnet units disposed on the second bag, the one or more magnet units disposed on the base, or the other magnet units 400 disposed on main body 200 by applying an external force exceeding the magnetic force between magnet unit 400 and the one or more magnet units disposed on the second bag, the one or more magnet units disposed on the base, or the other magnet units 400 disposed on main body 200

When magnet unit 400 is connected by magnetic force to one or more magnet units disposed on a second bag (e.g., as shown in FIG. 2), bag 100 and the second bag may help hold each other upright. When magnet unit 400 is connected by magnetic force to one or more magnet units disposed on a base (e.g., as shown in FIG. 3), the base may help hold bag 100 upright and may help prevent bag 100 from sliding when the base is attached to a portion of a trunk or truck bed. When magnet unit 400 is connected by magnetic force to another magnet unit 400 disposed on main body 200 (e.g., as shown in FIG. 4), the connected magnet units 400 may help hold bag 100 in the flattened configuration.

Magnet unit 400 may be a single magnet or may include multiple magnets. In embodiments where magnet unit 400 includes multiple magnets, the multiple magnets may be arranged, for example, as a chain of magnets. In some embodiments, the magnets of the chains of magnets can be disposed end-to-end. In some embodiments, the magnets of the chains of magnets can be spaced apart.

In some embodiments, magnet unit 400 is or includes a permanent magnet. Magnet unit 400 may be or include, for example, a rare-earth magnet, such as a neodymium magnet.

In the illustrated embodiment, magnet unit 400 is cylindrical shaped. However, magnet unit 400 is not limited to a cylindrical shape. For example, magnet unit 400 may be shaped as a cube, rectangular cuboid, sphere, arc, wedge, or other shape.

In some embodiments, for example, as shown in FIG. 1, magnet unit 400 may extend in a longitudinal direction (i.e., from a bottom of main body 200 toward a top of main body 200). This orientation may help maintain main body 200 in an upright configuration due the rigidity of magnet unit 400. In other embodiments, however, magnet unit 400 may extend in a transverse direction or in another direction.

In some embodiments, for example, as shown in FIG. 1, magnet unit 400 is elongated. In some embodiments, magnet 400 may extend at least half a height of main body 200. In other embodiments, however, magnet unit 400 may extend less than half of the height of main body 200.

In some embodiments, magnet unit 400 may be flexible or bendable. Magnet unit 400 may be flexible or bendable, for example, when magnet unit 400 is composed of a plurality of magnets.

In some embodiments, for example, as shown in FIG. 1, magnet unit 400 may be disposed on an exterior of main body 200. However, in other embodiments, magnet unit 400 may be disposed on an interior of main body 200 such that magnet unit 400 is generally not visible to a user from outside main body 200. In embodiments in which bag 100 includes lining 270 and outer shell 280, magnet unit 400 may be disposed between lining 270 and outer shell 280.

In some embodiments, magnet unit 400 may be secured to main body 200 by adhesive, sewing, stitching, gluing, heat sealing, or other suitable attachment mechanism.

In some embodiments, magnet unit 400 may be enclosed in sleeve 450 and sleeve 450 may be attached to main body 200 to secure magnet unit 400 to main body 200. For example, sleeve 450 may be attached to main body by sewing, stitching, gluing, heat sealing, or other appropriate manufacturing techniques. Sleeve 450 may be formed of any suitable material, including, for example, paper, woven or non-woven fabric (including, for example, polyester, polypropylene, nylon, cotton, hemp, burlap) or plastic. In some embodiments, sleeve 450 and main body 200 may be formed of the same material. In other embodiments, sleeve 450 and main body 200 may be formed of different materials.

In some embodiments, bag 100 includes four magnet units 400, each one fixed at a side edge 240. For example, as shown in FIG. 1, a magnet unit 410 is disposed on a side edge 242 located between a side panel 232 and a side panel 234, a magnet unit 420 is disposed on a side edge 244 located between side panel 234 and a side panel 236, a magnet unit 430 is disposed on a side edge 246 located between side panel 236 and a side panel 238, and a magnet unit 440 (not shown) is disposed on a side edge 248 located between side panel 238 and side panel 232. In some embodiments, one or more magnet units 400 may be disposed on a respective side panel immediately adjacent the side edge. In some embodiments, one or more magnetic units 400 may be disclosed in the middle of one or more side edges. In some embodiments, one or more magnetic units 400 may be placed at opposite ends of a side edge. Various combinations of the number and orientation of the magnet units 400 may be used.

Handle 300 may be fixed to main body 200.

In some embodiments, bag 100 includes two handles 300, each one fixed to an opposing side panel 230 of main body 200. As shown, for example, in FIG. 1, each handle 300 may have two ends and be fixed to main bag 200 at each of its ends.

Handle 300 may be formed of any suitable material, including, for example, paper, woven or non-woven fabric (including, for example, polyester, polypropylene, nylon, cotton, hemp, burlap) or plastic. In some embodiments, handle 300 is formed of the same material as main body 200. In some embodiment, handle 300 and main body 200 may be formed of different materials.

As shown in FIG. 2, for example, magnet unit 400 may be configured to connect by magnetic force to one or more magnet units 1400 disposed on a second bag 1100. Magnet unit 400 may also be configured to disconnect from magnet unit 1400 by applying an external force exceeding the magnetic force between magnet unit 400 and magnet unit 1400. When magnet unit 400 is connected by magnetic force to magnet unit 1400, bag 100 and bag 1100 may help hold each other upright. Additional bags 2100 and 3100, with one or magnet units 2400 and 3400, may be provided. Magnet units 400, 1400, 2400, and 3400 may be configured to connect to each other by magnetic force, and to disconnect from each other by application of an external force exceeding the magnetic force between them. In this way, multiple bags 100, 1100, 2100, 3100 can be arranged and secured to each other in a line, a row, or a matrix. Such arrangements may help hold bags 100, 1100, 2100, 3100 upright.

As shown in FIG. 3, for example, magnet unit 400 may be configured to connect by magnetic force to one or more magnet units 510 disposed on a base 500. Magnet unit 400 may also be configured to disconnect from magnet unit 510 by applying an external force exceeding the magnetic force between magnet unit 400 and magnet unit 510. When magnet units 400 and 510 are connected, base 500 may help hold bag 100 upright. In some embodiments, base 500 is attachable to a trunk of a car or a bed of a truck (not shown). When base 500 is attached to a trunk or truck bed and bag 100 attached to base 500, bag 100 may be more securely attached to the trunk or truck bed, thereby reducing the likelihood that bag 100 will slide. In some embodiments, base 500 may comprise a pre-existing portion of the vehicle that is magnetic.

In the illustrated embodiment, bag 100 is attachable to base 500 and/or additional bags 1100, 2100, and 3100. In this way, multiple bags may be attached to each other for stability as well as to a trunk or truck bed via base 500 for added stability. In some embodiments, bag 100 may be attachable to base 500 but not to additional bags 1100, 2100, and 3100. In some embodiments, bag 100 may be attachable to additional bags 1100, 2100, and 3100, but not to base 500.

Bag 100 may be attachable to base 500 while bag 100 is in the expanded configuration. Alternatively or additionally, bag 100 may be attachable to base 500 while bag 100 is in the flattened configuration in order to store bag 100. In some embodiments, additional bags 1100, 2100, and 3100, each in a flattened configuration, may be attached to bag 100. In this way, multiple bags may be conveniently stored.

As mentioned, bag 100 may be convertible between a flattened configuration and an expanded configuration. As shown in FIG. 4, for example, magnet unit 400 may be configured to connect by magnetic force to other magnet units 400. When magnet units 400 are connected by magnetic force to each other, the connected magnet units 400 help hold bag 100 in the flattened configuration. Magnet units 400 may also be configured to disconnect from each other by applying an external force exceeding the magnetic force between attached magnet units 400 so that the bags can be used independently of each other.
